When the attribute is defined but no value is set to it, the format provider cannot import the content and throws NullReferenceException.

Implement a mechanism that allows embedding font data when exporting documents.

The exception is thrown by the SystemFontsManager internal class from Telerik.Windows.Documents.Core, so it can observed when using RadPdfViewer, RadRichTextBox, RadSpreadsheet.

The reason is not clear, posssible causes are:
- Corrupted fonts after upgrade from Windows XP
- Enabling of Block untrusted fonts feature (https://docs.microsoft.com/en-us/windows/threat-protection/block-untrusted-fonts-in-enterprise )

The call stack is as follows:

System.TypeInitializationException: The type initializer for 'Telerik.Windows.Documents.Core.Fonts.SystemFontsManager' threw an exception. ---> System.IO.FileNotFoundException: Unable to find the specified file.
   at MS.Internal.Text.TextInterface.Native.Util.ConvertHresultToException(Int32 hr)
   at MS.Internal.Text.TextInterface.FontList.get_Item(UInt32 A_0)

   at System.Windows.Media.Fonts.TypefaceCollection.<GetEnumerator>d__11.MoveNext()

Workaround: 

Manually delete all registry key values in Computer\HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows NT\CurrentVersion\Fonts pointing to files outside of the Fonts folder.

In some cases when an image is copied from an external source and pasted in the rich text box, the image is not displayed. This is caused by the Clipboard.GetImage() method used internally by the control. 

To work this around, you can subscribe for the CommandExecuting event of RadRichTextBox and manually get the image from the clipboard.

private void Rtb_CommandExecuting(object sender, Telerik.Windows.Documents.RichTextBoxCommands.CommandExecutingEventArgs e)

{
	PasteCommand command = e.Command as PasteCommand;
	if (command != null && (Clipboard.GetData("DeviceIndependentBitmap") != null))
	{
		//Get the image stream from the clipboard.
		//You can check the following blog post for an approach which you can use to get the image properly:
		//https://www.thomaslevesque.com/2009/02/05/wpf-paste-an-image-from-the-clipboard/
		this.radRichTextBox.InsertImage(imageStream, "jpeg");
		e.Cancel = true;
	}
}	

Using Microsoft Pinyin IME for typing in the RichTextBox causes FatalExecutionEngineError exception. 

Actually, when we go to image editor from the RadRichTextBox, we've got the original image's size but not the width and height in the document. When we need to format pictures of a document with equal size, we are using the document's size, not the picture's size.

Thanks 

With a picture of original size like this : width 2 800 and Height 1376. On the screen the picture is around 470 by 230. If I go to the Image Editor, it shows me the picture size itself but not the area size used by the picture. It is a good thing to have the original picture's dimension but we work with the dimension used in the document. So, could you do something to resize the picture used in the document.

In my samples, you'll see my picture in a document (ie1), what I see when I go in the Image Editor (ie2) and, when I go to the Resize section (ie3). Suggestion, put the original image's dimension on the top of the right corner in the resize section. The width and Height should show the dimension in the document.

Thanks a lot, 

Typing in Find dialog is not possible when having an ElementHost in a WinForms Windows to host a WPF User Control which contains the RadRichTextBox.

If I setup the richtextbox content through the UI as shown in P1.png and try to restore it by pasting the generated html, I get instead P2.png. Expected to be the same. 

I attached the sample project. We're using the recommended settings to use the same html in telerik reports, but can't find the reference on your site, it used on the on this link http://docs.telerik.com/devtools/wpf/controls/radrichtextbox/import-export/features-import-export-settings#htmlformatprovider

 

The same issue is observed with heading styles. 
The HtmlExportSettings property PropertiesToIgnore can't be used to control how the paragraph or character properties of a list will be exported.
Steps to reproduce:
Create a document with a list of different levels.
Set fp.ExportSettings.PropertiesToIgnore["li"].Add("margin-left");
Export to HTML.
Observed: The PropertiesToIgnore doesn't work for paragraph properties of a list.

The text for the Documents_SpellCheckingDialog_ChangeAll key must be "Changer tout" instead of  "Chanter tout".

Finding text with regex for the last paragraph is not possible. This is caused by the fact that the search treats the last paragraph symbol as the last paragraph.

Character properties applied on the last paragraph symbol for a paragraph in a list, e.g. font size, are not exported to HTML when StyleExportMode is Inline. 

As a side effect, when the document is imported back, and the text of the bullet is deleted, its properties switch back to the default ones.

Workaround: Change the styles to export as inline properties:
 
Please be aware that this may cause side effects, as described in this issue: RichTextBox: Character properties of the paragraph symbol are exported to HTML for the whole list item when StyleExportMode is Classes

Nested ol/ul list should be inside a <li> element of the list in which it is nested. For example:

<ul>
<li>Option A</li>
<li>Option B
  <ul>
    <li>Sub 1</li>
    <li>Sub 2</li>
  </ul>
</li>
</ul>

 

The character properties applied on the last paragraph symbol for a paragraph in a list (e.g. font family), are exported to HTML for the whole paragraph which is in the list. 

As a notable side effect, when such HTML is imported, the default font size for a paragraph in a default bullet list changes to Symbol.

Regression: The bug is introduced in 2016_2_613.


Workaround: Change the styles to export as inline properties:

but be aware that this may cause issues as described in the related RichTextBox: Character properties of the paragraph symbol are not exported to HTML when StyleExportMode is Inline

Currently the logic that sets ChangeFontSizeCommand up relies on RadComboBoxItem.Tag to be used as a command parameter. Although FontSize semantically is a numeric value, the  command only works with string parameters.

The event is not fired when updating the IncludePictureField fields. It is also valid when the fields are in Header or Footer. The issue is a regression in R1 2019.

The UpdateAllFields() method of RadDocumentEditor can be invoked so the event can be fired and give you the possibility to update the images.

HTML parser does not handle the described scenario properly. Nevertheless this is not a valid css snippet, app should not be brought to inoperable state.

I want to import a FlowDocument into IDocumentEditor in order to obtain a RadDocument which I can convert to PDF.

Add ability to select last paragraph symbol in Section and TableCell.  Currently there is no document position after the last paragraph symbol in a document/section/table cell. This means it cannot be part of a DocumentSelection.
